Specification ot Letters Patent. Patented Aug. 13, 1918.

Application led April 24, 1917. Serial No. 164,149.

To all whom t may concern.'

Be it known that I, FREDERICK H. MYERS, a citizen of the United States,residing at Barberton, in the county of Summit and State of Ohio, haveinvented new and useful the device is being moved from place to place,and also arranged when moved to an appropriate position to serve as aguide or gage for controlling the depth of insert on the teeth in thesoil.

The invention also contemplates the provision of a pair of arms capableof being laterally `spread apart, said arms equipped with cultivator,teeth whereby the width of the Zone or area engaged by `the eultivatoror device may be varied at will.

lVith the yforegoing and other objects in view,..the invention consistsin the novel constructi'm .combination and arrangement ofy artsconstituting the invention to be herelnafter. specifically .describedand illustrated in the accon'ipanyig drawlngs which form a part hereofwherein is'shown the preferred embodiment of the invention, but it'is tobe understood that changes, variations and modifications can be sortedtowhich come within the scope of t ematter hereinafter claimed.

In the drawings in which similar reference numerals indicate like partsin the different figures,

Figure l'is a perspective view of a cultivator embodying the presentinvention.

. Fig. 2 is a plan View of the same.

Fig. 3 is a vertical central sectional view taken approximately on line3 of Fig. 2.

Fig. 4 is a vertical transverse sectional view taken approximately online 4 of Fig. 2.

Fig. 5 is a detail of mechanism employed for raising and lowering thedevice, and

Fig. 6 is a detail view taken on line 6 of Fig. 4 showing the means forholding the supports for the cultivator teeth.

Referring specifically to the drawings the device embodies a main. beam1 provided with a central longitudinal slot 2 which divides the frontend of the beam into two parallel spaced members 3 andV 4, the front.ends of which are secured together and held in spaced relation by meansof a cross bar 5 secured to the members 3 and 4' by bolts 6. The members3 and 4 are respectively provided with downwardly-extending parallelanges 7 and 8 (see Fig. 4). The rear por- 'tion of the beam 1 isprovided With an integral T-head embodying 'lateral projections,

9 and a central rearwardly-pro]eeting lug 10. The extensions 9 and thelug 10 are vertically a ertured to constitute bearings for the shan rs11 of cultivator teeth 12. The cross bar 5, at the forward end of thebeam 1, is rovided at each end with a pairof ears 13 with the ears ofeach pair in spaced relation and with all ears arranged at aninclination to the beam 1. Pivotally mounted in each pair of ears bymeans of members 14 is ahandle 15 the rear portions of which areconnected by a cross bar or rod 90 which extends through suitableapertures in the handles and cooperates with a U-shaped brace 16 theendsof which are provided with a series of apertures to receive theprojecting ends of the bar 90 for holding the handles in a desiredposition. 'The central portion of the 'U-shaped brace is com' nected tothe upper face of the T-shaped head at the rear endy of the beam 1.Pivotally secured to tlie under face of the cross bar 5 at the forwardend of the beam 1,

"arma-pair of rocking arms 17 and 18 conor lateral wall andihese Shanksare clamped isis through which extends a bolt 92 the upper wall by meanso U bolts 2O of'- ordinary construction with threaded ends and providedwith nuts for the clamping o eration. The shanks of all the teeth on t edevice are constructed substantially alike and eachconsists of a tubularsleeve 21 each provided with a head 22 (see Fig. 4) and each having theopposite end threaded to receive f a nut 23', which is adapted to clampone end of the cultivator tooth and hold it against the lower end of thesleeve 21, and by this i rovision when the sleeve 21 is clamped by ashaped bolt 2O the. bolt 92 may be rotated horizontally to secure adesired osition for the cultivator tooth carried there y and also A lthesleeve may be raised or lowered without vdisturbing the connectionbetween the bolt 20,

92, the Sleeve 19 and -the cultivator tooth.

,'Iltl'the instance of the Shanks for the cultivato'r teeth 12 where thes hanks pass through the openings in the head 9 of the beam 1, the

set screws 11 engage the sides of the sleeves 21 and do not interferewith the manipulation of the cultivator teeth.

Mounted on tlie` up er face of the rear rtion of the beam 1 is a plate30 the front ace .of which is at right angles to the loneoffgitudinalaxis of the beam 1 and with the rear face or edge of the plate arcuatelyfashioned. This late is wider than the upper face of the lIn 1 andoverhangs the saine. The plate 80 is adapted to slide 1on-Y .gitudinallyof the upper face ofthe beam 1 and is held from lateral movement thereonby means of two guiding strips 31 secured to the under face of themember 30 and positioned on opposite sides thereof and held inositionfby holdin means 32. These guiding strips 31 are eld.in s cedrelation with respect to the. under ace of. the plate 30 by spacingblocks 33 so that the iding strips 31 form in connection with t e plate30 and spacing blocks :33 a pair of channels which receive theoutwardlyextending anged Yupper walls of the beam 1 and form' channelsfor this purpose'to rmit the longitudinal: sliding of the p atel withoutlateral movement thereof. Mounted on the upper face ofthe front portionof the plate 30. isa=T-headed block 34 pms vided with overhanginglateral ends this block is also provided with a central threadedaperture in which is received a@ 'threaded shaft 35 the front is adaptedto engage an abutment 36 "-"i end of 'which time in the slot e of thebami and eid there by any suitable holding means such ne rivets. Theopposite end of the shaft is prol vided with a manipulating head 37 andthis end of the shaft is'suported in a bearing v88 mounted on the u perface of the rear end of the beam 1. he shaft 35 bears adjacentto thebearing 38 a collar 39 to prey to the under face of one ,of the linksand vent the shaft when manipulated from moving to the left in Fig. 2and the abutment 86 prevents movement in the lopposite direction. Thelateral ends of the blockA 84 are separated from the upper face of theplate 30 to provide a space through which extend pivots 95 for links 40and 41 for laterally oscillating the teeth-'bearing arms 17 and 18.Connecting the member 34 with the arm 18 is a link 40 and a similar link41 connects the member 34 with the free end of the arm 17. The free endsof the arms 17 and 18 are enlar ed and preferably are formed solid andin tese end portions are pivotal pins 42 each projecting above and belowthe upa' per and lower faces of the ends and the links t 40 and 41 areconnected to the upper pro jecting ortions of these pins respectively.

The links 40 and 41 are identical and hence a description of one isbelieved to be suilicient for the understanding of both. Secured to theunder face of'eacli link is a combined guiding and supporting member 44the central portion of which is fastened with the outer portion of eachbrace extending under the respective free end of one of the arms 17 or18 and operatively connected with the downwardly-projecting end of thepivot 42. The inner ends 45 of the braces 44 are fashioned to engageunder the plate 30 and to serve as means for preventing any upwardmovement of the outer ends of the arms 17 and 18 and by their engagementwith the plate 30 they permit lateral and horizontal but not verticalmovement of the links 40 and 41 to which they are attached. The innerends 45 of the member 44 in connection with the links 40 and 41 formjaws which freely receive the plate 30 and hold the arms 17 and 18 fromvertical movement while permitting the tree swinging of the outer endsof the links in shifting or oscillating the arms 17 and 18. Fromtheforegoing `it .will be seen that when the screw 35 is rotated the plate30 is moved longitudinally of the beam 1 thereby swinging the outer endsof the links 40 and 41 inwardly b -A entupon the position which itisdesire that` cultivator teeth carried by these arms mums. i"."Thfrilnner or' means by which the culti-.

mbv.- `plliee wi be` transported from place to ut causing the teeth toengage the groundv and also which serves as a'gage cally'alike in alland each L-shaped lso for regulating the depth of the furrows cutv curedtogether by means of bolts 54. Be-

1,275,5ss i provide a central groove or channel 52 between them. Thisrunner is so fashioned that the front is upwardly bent in arcuateformation to provide a head or front 53 and the two members of therunner are setween the two members 50 and 51 are spacing blocks 55through which pass bolts 56. Extending between the opposing upright orvertical flanges of the members 50 and 51 are a plurality of pins 57 towhich are attached links the upper ends of which are respectivelyconnected with pins 59 extending between the depending flanged portionsof the beam 1. These links 58 will 'at all times be parallel withrespect to each other and. they serve to connect the beamand runner inthe same manner that the members of a parallel ruler are attached tonach' other. Extending between the flanged members of the beam 1 is apin G0 on whichis pivotally mounted an operating lever (il the lower endof which is connected with a piu 62 extending ybetween the uprightflanges of the members 5() and 51.

The upper end of the lever 61 bears a handie G3 to which is pivoted asecond lever or controller {i-l to one end of which is con nrcted a wireof which in turn is connected with a lockt [Sti suitably mounted forlongitudnal shifting: in a slot. (37 in the lever 61 and held againstlateral movement by guiding pins, 37s. 'lhe lock ilu is normally forced,inwardly toward the pin (3() by ineans of a eoiird spring lili. Mountedon opposite sides of thcslot E! on the brain l are quadrants 70 providedon their arcuate faces with tccth'or notches 71 with the notches of thetwo quadrants in transverse alinement with each other. The lock fifi isof sufficient width to engage the alined notches in both operating lever(il is raised to ils upper po silion as shown in dotted lines in lfig.Cl whirl. causes the runner l'o be lorrod downwardly so4 that the .lowerworking lare thiireof will engage the ground and raise the teeth of thecultivator from contactv therewith. The cultivator is then dra ged orpushed to the field of operation an the operating lever 61 is thenIdepressed suffi` eiently to permit the teeth to engage the ground toany preferred or desired depth. he operator then determines from aninspection of the ground to be cultivated, the relative needed positionsof the two arms 17 and 18 and b manipulating the screw 35 he so adjustst e arms that the teeth carried thereby will perform the cultivatingoperation properly and course, the relative positions of the two arms 17and 18 may be changed at any time. If it is desired for any reason tochange the vertical position of the various teeth with respect to theframe of the cultivator the U-shaped bolts 19 are released and the teethadjusted and the U-shaped bolts retightened holding the teeth in theproper position' and the same operation is employed with respect to theteeth carried by the'rear end or head of the beam 1, only in4 thisinstance the set screws 11 are released sufficiently to permit theadjustment of the teeth. It will be obvious, of course, that the teethcan be rotated on their axes aswell as raised vertically, so as to causethem to engage the ground at an inclination, if desired.
